I found online instructions for a quick way to sharpen blades. I studied them briefly and then thought, confidently "I can do this." So I ordered lapping compound, 240 grit, figured out how to take off the E ring and wheels and pinions. And then came the removal of the pawls. The instructions didn't note that you need to remember the direction of the pawls before you remove them. I paid no attention to the direction of the pawls as I removed them. Uh oh.
Time for plan B.
From wikipedia:
Ratchets consist of a gearwheel or linear rack with teeth, and a pivoting springloaded finger called a pawl (or in horology a click[1]) that engages the teeth. Either the teeth, or the pawl, are slanted at an angle, so that when the teeth are moving in one direction, the pawl slides up and over each tooth in turn, with the spring forcing it back with a 'click' into the depression before the next tooth. When the teeth are moving in the other direction, the angle of the pawl causes it to catch against a tooth and stop further motion in that direction.
